LETTER-SCALE.

Application filed March 13, 1899. serial No. 708,869. (No model.)

To all whom, it may concern.-

Be it known that I,WILLIAM ESCHEMANN, a citizen of the United States,residing in Philad el phia, Pennsylvania, have invented certainImprovements in Letter-Scales, of which the following is aspecification.

The object of my invention is to provide a letter-scale which isoperative without the use of springs and is of such a simple charactorthat it can be made cheaply enough to be available for use as anadvertising medium for gratuitous distribution. This object I atlain inthe manner hereinafter set forth, reference being had to theaccompanying drawings, in which Figure 1 is a front view of aletter-scale constructed in accordance with my invention. Fig. 2 is arear view of the same. Fig. 3 is an enlarged perspective View of thehook or pin from which the scale is suspended. Fig. 4-. is a perspectiveview illustrating a modification of one of the parts of the scale; andFigs. 5, 6, 7, and 8 are views illustrating other forms of scaleembodying the main features of my invention, Fig. 7 beinga rear view ofFig. 6.

The scale shown in Figs. 1 and 2 comprises three main parts-namely, theface-plate 1, the three-armed lever 2, and the weight 3, all of whichcan be made from sheet metal by inexpensive operations, so that the costof the device can be reduced to a minimum. The face-plate has at the topan eye 5, whereby the scale may be suspended, and in order to preventthe swinging of the scale on the suspending pin or book the eye 5 has atthe top a rectangular notch 6, which is intended for the reception of arectangular portion 7 upon the suspending pin or hook, Fig. 3, wherebythe scale is rigidly held in vertical position.

Extending part way around the faceplate 1, adjacent to the periphery ofthe same, is a graduated scale 4:, divided into ounces and half-ounces,andin connection with this scale operates a pointer 9,consisting of theforwardly and downwardly bent end of an arm 10 of the three-armed lever2, which is disposed behind the face-plate and is hung so as to be freeto swing upon a pin, lug, eyelet, or other suitable central support 13on said face-plate.

The depending arm 11 of the lever 2 has at its lower end an arm 14,carrying the weight 3, said arm 14 being pivoted to the lower end of thearm 11, so that it always preserves its vertical position irrespectiveof the angle assumed by said arm 11. If desired, the weight may besecured directly to the lower end of said arm 11, the swingingconnection being preferred, however, as the more eflicient of the two,because as the arm 11 swings upward it does not carry the weight so farfrom the axis, and hence does not increase the power of the weight tothe same extent as if the latter were attached directly to the arm 11.To the third arm 12 of the lever2 is connected the upper end of a chain15, which has at its lower end a spring-clip 16 of any ordinaryconstruction for grasping and retaining the letter, package, or otherobject to be 7 weighed.

In some cases I may use in place of the chain and clip an arm 17, withclasp 18 at the lower end, as shown in Fig. i, one end of the claspbeing bent upward, so as to form a hook 19, which serves as a means ofsuspending letters or packages of such size or shape that they cannot beheld by the clasp.

The arms 11 and 12 of the lever 2 are so disposed angularly in respectto each other that when the arm 11 occupies its normal vertical positionthe arm 12 will be at the limit of its upward movement, and any weightexerted upon the outer end of said arm 12, tending to pull down thesame, will cause lateral deflection of the arm 11, the power of theweight gradually increasing as said arm 11 departs more and more fromthe normal vertical position. v

The device described can be so cheaply made that while it constitutes asufficiently accurate scale for ordinary use its cost is well within thelimit of articles intended for free distribution for advertisingpurposes, the utility of the device rendering it exceptionally availablefor such use.

A simpler form of my improved scale is that shown in Figs. 6 and 7. Inthis case the eye 5 is formed upon a pointer-arm 10 and the face-plate 1is centrally pivoted upon said arm and has hung from it the Weight 3,the clip 16 being suspended from the face-plate by means of a wire,chain, or other connection 15. The face-plate 1 thus becomes theswinging element and carries the letter-receiver and the weight. Thegraduated scale may, if desired, be carried by the arm 10, so as tooperate in connection with a pointer on the face-plateas shown,forinstance, at e in Fig. 8.

Having; thus described my invention, I claim and desire to securebyLetters Patent A letter-scale consisting of a face-plate and an arm,said parts being pivoted directly together, one of said parts having agraduated scale and the other a pointer, and one of them carrying adepending weighted and in-
